Mass Effect 3 screenshots show new baddies, expert posing

Here's something you can try at home. First, set up a camera. Then, grab a futuristic rifle (use a pretend one if there aren't any lying about). Now turn left until you're at a right angle to the lens.

Good. Now get a friend to stand behind you facing in the opposite direction. Then get a third friend to stand slightly behind both of you off to the other side.
